Discussion on policy-making and of effective policy-making mechanisms is once again emerging in the policy literature. Much of the debate in the past focused on whether the method applied in the physical sciences was appropriate for policy and policy-making. Current debate appears to be reverting to some form of rationalism in so far as good policy processes are seen to yield the most effective results. This article discusses what appears to be a revival of rationalism — the process-oriented policy cycle. The article argues that there is little doubt that effective policy-making requires good process but it is erroneous to suggest that the content of policy, particularly in the case of contentious decisions, is derived from the policy cycle itself. It is argued further that the policy cycle is not a substitute for the actual making of decisions but an administrative and bureaucratic mechanism for effectively setting in place a process once the difficult decisions have been made. 相似文献

Disordered eating is highly prevalent during adolescence and has a detrimental effect on further development. Effective prevention programs are needed to prevent unhealthy developmental trajectories. This study evaluated the efficacy of the POPS-program (POtsdam Prevention at Schools), a universal school-based eating disorder prevention program for adolescents. In a cluster-randomized design, we compared the intervention group receiving the prevention program to a waiting control group. Outcomes included indicators of disordered eating and relevant risk factors for eating disorders (body dissatisfaction, internalization of the thin ideal, perceived media pressure, perfectionism, emotional element of exercise, social comparison, and perceived teasing). Questionnaires were administered at the start of the intervention, 3 and 12 months post intervention. At baseline, 1112 adolescents aged 10 to 16 years participated (49% girls; 51% intervention group). Intention-to-treat analyses with the complete data set and per-protocol analyses as a completer analysis were performed. The intervention group showed a more favorable course compared to the control group regarding all observed risk factors for eating disorders except for perceived teasing. Effect sizes were small but comparable to other primary prevention programs. At 1-year follow-up, a small but significant effect on disordered eating was observed. Results of the per-protocol analyses were mostly confirmed by the intention-to-treat analyses. Results were promising for both genders although girls benefited more regarding disordered eating and internalization of the thin ideal. Further studies are warranted examining successful program elements and whether gender-specific programs are needed. 相似文献

The transition to high school has been identified as a potentially difficult time in adolescents’ lives. Reductions in both
academic and social functioning often accompany this transition. While these effects have been documented in urban youth,
the move to high school has not been extensively studied in rural minority youth. Toward that end, the academic grades and
substance use in ninth grade of 447 (184 male and 263 female) African-American adolescents from two rural counties in a state
in the deep South were examined in relation to configurations of adaptation from sixth through eighth grade. Results indicate
that individual with consistently positive patterns across middle school had higher grades and lower rates of substance use
compared to individuals with persistent difficulties or those that transitioned to problem behavior. Many individuals who
improved in their patterns of adaptation had relatively high grades, but also rather high rates of substance use in the ninth
grade.

Coalitions of free-marketeers, politicians, and environmentalists increasingly are turning to the use of market-based incentives in formulating environmental policy. One promising application of market-based incentives is in the management of residential municipal solid waste. This article focuses on unit-based pricing programs established in conjunction with community recycling programs. Using data gathered through telephone and mail surveys of 21 cities, we demonstrate the strong potential for unit pricing to improve the efficiency of residential solid waste management. 相似文献

This study examines the importance of victims’ expectations of the police, the decision to arrest, and voluntary contact on
satisfaction ratings of the police in domestic violence cases. Based on results from past research and modern police policy,
several hypotheses are tested including: fulfilled expectations, offender arrests, and voluntary contacts resulting in positive
satisfaction ratings of the police. To investigate these predictions further, the present study utilizes data from a national
study on violence against women in the United States. Logistic regression analyses indicate that fulfilled expectations and
the arrest decision are important to positive satisfaction ratings. Findings also indicate that involuntary, not voluntary,
contact with the police leads to higher satisfaction ratings. 相似文献

Gamma-Hydroxybutyrate (GHB) overdoses cause respiratory depression, coma, or even death. Symptoms and severity of poisoning depend on blood-concentrations and individual factors such as tolerance. A retrospective case study was conducted, evaluating GHB intoxication cases. GHB-concentrations in blood and urine were determined by gas chromatography-mass spectrometry (GC-MS) along with, in part, via enzymatic assay. GHB-concentrations, demographic data, and additional drug use, as well as specific clinical information, were evaluated. The correlation between GHB-levels in blood and associated symptoms were examined. In total, 75 cases originating from the Emergency Departments (EDs) of Hamburg and surrounding hospitals were included. Fifty-four of the patients (72%) were male. The mean GHB-concentration in blood was 248 mg/L (range 21.5–1418 mg/L). Out of the group with detailed clinical information (n = 18), the comatose group (n = 10/18) showed a mean of 244 mg/L (range 136–403 mg/L), which was higher than that of the somnolent and awake patients. Of the comatose collective, 70% (n = 7) showed co-use of one or more substances, with the additional use of cocaine being the most frequently detected (n = 5). In conclusion, a moderate dose-effect relationship was observed, although, there was some overlap in dosage concentration levels of GHB in awake and comatose patients. In GHB-intoxication cases, co-use was common as were clinical effects such as acidosis, hypotension, and impact on the heart rate. Timely analytical determination of the GHB-concentration in blood could support correct diagnosis of the cause of unconsciousness. 相似文献
